ROAD-GRADER.

Specification of Letters Patent.

Application filed August 241, 1908.

Patented April 13, 1909.

Serial No. 450,040.

To all whom it may concern:

Be it known that I, SAMUEL A. ULRICH, a citizen of the United States, residing at Mendota, in the county of Putnam and State of Missouri, have invented certain new and useful Improvements in dead-Graders, of which the following is a specification, refer ence being had therein to the accompanying drawing.

This invention relates to improvements in road graders, and has for its object the production of a scraper which can be adjusted to be used as a drag or road grader.

Another object of this invention is the production of a scraper which is comparatively simple in construction, and easy to handle or operate.

-With these and other objects in view, this invention consists of certain novel constructions, combinations, and arrangements of parts, as will be hereinafter fully described and claimed.

In the drawings: Figure 1 is a perspective View of my scraper. Fig. 2 is a top plan View of my scraper. Fig. 3 is a front view. Fig. 1 is a section taken on line 4-4, Fig. 3, looking in the direction of the arrow. Fig. 5 is a sectional view taken on line 55, Fig. 3,100king in the direction of the arrow. Fig. 6 is a detail perspective of the brace for the curved guide. the guide plate regulating device.

Referring to the drawings by numerals, 1 designates a scraper body, which I shall hereinafter designate as a scraper plate. To the front of the scraper body 1 is secured an angle-member 2, and the upper flange of the angle-member 2 fits in the bifurcated end 3 of draft pole 4, and said flanged portion is held in said bifurcated end 3 by means of a bolt or rivet passing through said bifurcated end and said flanged portion. The ends 6 of the curved guide plate 5 are bent down wardly and secured to the rear of the scraper plate 1. The guide plate is also secured to the top of the scraper plate 1. An anglebrace 7, shown in Fig. 6 in detail, is secured at its downwardly-extending end 8 to the scraper plate 1. The angle-brace 7 constitutes a flat body portion, which terminates into a reduced U-shaped portion 9, at its upper end, the U-shaped portion constituting a hook passing through the guide plate 5.

Fig. 7 is a side elevation of i The guide plate 5 will'be clamped between the two parallel portions of the U-shaped portion 9, and in this manner the plate cannot become accidentally detached from the brace 7 A bracket 10 is secured to the upper face of the draft pole l, and said bracket constitutes a guide for the guide plate 5. The plate 5 is provided with a plurality of apertures 11, and a pin 12 passes through the bracket 10 through one of the apertures 11 in the guide plate 5, and securely locks the guide plate 5 in the guide 10. In this way the scraper plate can be adjusted to any angle, and it will be seen that in this manner the device may be used either to level a road, or to act as a drag or grader. Upon the pole 4 and in front of the bracket 10 is also placed a bracket 18, which bracket retains the whiffle-tree upon the pole.

An inverted U-shaped member 1 1 strad dles the upper ed e of thescraper plate 1,

and said member 14: is provided with short leg 15, which is secured to the front of the scraper plate, and a long leg 15 which. is secured to the rear of the scraper plate. The long leg 16 extends nearly the entire hei at of the scraper plate 1. To the rear of the scraper plate 1 is also secured a bracket 17, which bracket acts as a guide for the le or standard 18. The long leg of the inverted lei-shaped member 1% acts as trr. for the le or standard to work upon. Lpon the lower end of the stands; 3. 18 is posit oned a spur 19, which spur acts to prevent the s .aper from sliding when the scraper plate 1 is raised by the means hereinafter described. The standard 18 is provided with an elongated slot 20, in which is pivotally mounted a lever 21. Secured to the inner side of the standard 18 is curved rack. 22, which is adapted to be engaged by spring-pressed pawl 23, carried by the lever 21.. The L shaped member 24 is connected to the it shaped. member 1a and to the lower end of the lever 21. The ends of the U-shapcd member 24 terminate int-o eyes 25, and a rivet or bolt passes through the eyes 25 and the lower end of the lever 21, and connect said U-shaped member to said lever 21.

It will be seen that I have provided a scraper which can not only be adjusted at a certain angle, by means of the guide plate 5,

ii I) but also provide a scraper which is provided with a scraper plate or body which can be raised entirely from the ground and be supported by the standards 18, or can be raised only at one end, by means of one of the levers 21.

A rack plate 26 is positioned upon the draft pole 4, and pivotally mounted upon the rack plate 26 is a lever 27, which is provided with a spring-pressed pawl, which pawl engages the teeth upon the rack plate 26 and locks the lever 27 in an adjusted position. The lever 27 is provided with a lower bifurcated. end 28 which straddles the draft pole 4 and is positioned directly under the guide plate 5. The guide 10 upon the draft pole is provided with a slot 29, through which passes the lever 27. This slot is positioned in the guide 10 to allow free movement of the lever 27. As the guide plate is connected to the scraper plate 1 it will be seen that when the guide plate is raised or lowered by means of the lever 27 the angle of the scraper plate 1 will be changed or regulated. It will also be seen that by the use of this lever the angle of the scraper plate 1 can be adjusted so as to act as a scoop, or merely as a scraper.
